Excess sweating, also known as hyperhidrosis, is a common problem that many of us suffer from. If you are bothered by severe sweating, we could have the solution for you.

How do Botox injections work?

Botox works by blocking the nerves responsible for activating your sweat glands. Normally, your nervous system activates your sweat glands when your body temperature rises. This is how your body automatically cools itself. In people with hyperhidrosis, however, the nerves that signal the sweat glands are overactive.

When you receive Botox injections directly into the area of your body that commonly sweats, your overactive nerves are essentially paralyzed. When your nerves can’t signal your sweat glands, you don’t sweat. However, Botox only prevents sweating in the specific area where it’s injected.

Where is Botox used?

Currently, Botox has only been approved for the treatment of underarm sweating. In studies, Botox was extremely effective in treating underarm sweating.

Studies have found that Botox successfully treats sweaty palms in 80 to 90 percent of cases.


What to expect after treatment

You can resume your normal activities immediately after receiving Botox injections. It will take between two and seven days for you to stop sweating in the treated area. It can take two weeks for total dryness.

The effects of Botox are temporary, which means you’ll need more injections in the future. For underarm sweating, dryness can last anywhere from four to fourteen months. Results may not last as long for the hands and feet, and you may need to repeat your treatment in about six months.

About two weeks after your treatment, once you have seen the full effects of the Botox, you should see your doctor for a follow-up appointment. At this appointment your doctor can perform any “touch ups” of missed spots.

Bottom line

Botox is a highly effective treatment for excessive sweating. For many people, it drastically improves their quality of life.
